TUNING ATTACHMENT FOR CORNETS.

*SFECIFICATION forming part; of Letters Patent No. 331,679, dated December 1,1885.

' Application filed April 21, 1885. Serial No. 162,942. (No model.)

T0 (6 whom it may concern:

Be it known that I, WADE BUOKLEY, a citizen of the United States, residing at Easton, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in an Attachment for Oornets, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improve ments in cornets and other wind-instruments of that class; and it has for its objects to provide for readily, rapidly, and conveniently changing the pitch of said instruments as occasion may require, whereby the necessary change of pitch in an ordinary instrument may be made by the musician, as more fully hereinafter specified. These objects I attain by the means illustrated in the accompanying drawings, in which Figure 1 represents a side elevation of my improved device with the parts arranged to produce the highest pitch; Fig. 2, a similar View with the parts arranged to produce the lowest pitch; Fig. 3, a detached View of a lock-latch to secure the parts when arranged for the low pitch, and Fig. 4 a view of a cornet, showing my invention applied thereto.

The letter A indicates a tube of suitable length, the lower end of which is provided with a tapered projection, B, adapted to fit in the forward end of the cornettube, in the place of the ordinary crooks of the instrument. Within said tube is accurately fitted a tube of smaller diameter, which is adapted to slide in the outer tube. The said inner tube at its outer end is provided with a crossca-p, O. From the extending lateral arms D of the same project the longitudinal guide-bars E, which pass through a similar cross-cap, F, on the upper end of the outer tube before mentioned. These guide-bars at their lower ends are provided with stops or studs G, which limit the movement of the parts, so as to change thepitch from A natural to Bflat, or vice versa. To the outer lower end of the outer tube is secured a spring, H, which serves to lock the two tubes when drawn out to their fullest extent, and which can be manipulated by a lug, I, in order to change the parts when desired.

In operation my device is placed in the position of the ordinary mouth-piece of the cornet, and the ordinary mouth-piece of the same placed in the upper section of the device. WVhen required to change the pitch of the instrument, it will be seen that the attachment has only to be lengthened or contracted. It will be further seen that the attachment may be applied to any cornet or other similar wind-instrument without alteration of the same, thus obviating the objections heretofore experienced.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination, with the inner and outer tubes of the attachment, adapted to be secured to the forward end of the tube of a cornet, of the guide-rods, and the stops at their ends to limit the movement of the respective tubes, substantially as and for the purposes specified.

2. The combination, with the sliding tubes and the guide-rods, of the lock spring or latch whereby the two are held in proper relative positions, substantially as and for the purposes specified.

In testimony whereof I affix my signature in presence of two witnesses.
